Hi - I'm trying to program the Thingy52 using my nRF52840 DK and Macbook Pro. I've got the Thingy connected to the DK via the 10-pin cable. The first time I ran nrfjprog on it, I used a --chiperase option and ever since then I'm not able to see any signs of life on the Thingy - no led activity, no BLE advertising I can see in nRF Connect. The last 3 commands I ran are shown below - I was trying to give it a softdevice, an application hex file that came from a build I just did on the Thingy SDK with no source changes, and reset it. Why isn't it working? Do I need to give it a bootloader - is that the issue?
nrfjprog --family NRF52 --program ~/nRF5_SDK_15.2.0_9412b96/components/softdevice/s132/hex/s132_nrf52_6.1.0_softdevice.hex --chiperase --verify
nrfjprog --family NRF52 --program ~/thingy_sdk_v2.1.0/project/pca20020_s132/armgcc/_build/nrf52832_xxaa_s132.hex --sectorerase --verify
nrfjprog --family NRF52 --reset
